(Yeah, so maybe I am bored this morning... )
Here is an age old (well, I am at an old age and always wondered about it) musical question:
What came first the chick or the egg, man?
In late 1967 the Rock-and/or-Roll music scene had two songs from two very popular groups that had similar sounding refrains. You may never have heard of either of these groups, but, trust me, when I was a little kid they got a little airplay on the AM radio. The first group was two kids from New York calling themselves “Garfinkle & Solomon” (or something close ‘nuff) and the second group were some Scousers that didn’t even last as a group into the 70’s. (So, you know they musta been a buncha hacks.)
In “Mrs. Robinson” Artie and Paulie sing the nonsensical phrase "Koo-koo-kachoo". (Additionally, they mention Dom DiMaggio’s older brother… John… George… Jerry… something like that. He may have played a little AAA Baseball or something, too. I think that guy was only famous for marrying Marilyn Monroe and drinking lots of Coffee, though. Everyone knows the only reason the line in the song was not “Where have you gone Ted Williams?” was because the meter just was not right.)
The group of Scousers (calling themselves “the Beets-less” for some reason; perhaps the name “Turnips-more” was already taken) had a song called “I Am the Walrus”, wherein their nonsensical phrase was "Goo Goo G'Joob".
Truth be told, the Scousers song was released on November 24th, 1967 and New York boyos song was included in the movie "The Graduate" which was released on December 21st, 1967. However, they really couldn't have been influenced by one another as they would have had to be written well before the actual release and the similar sounding nonsensical phrases are just a rather silly coincidence.
